SCARF-EIN GUARD.

Specification of Letters Patent.

Application filed September 9, 191.1. Serial N o. 648,425.

HARDIE, a

the city of Yo.n'kers,'inthe county of' Westchester and State of New York, have invented certain new and useful Improve-l ments in Scarf-Pin Guards, of lwhich the wherein I have shown my invention ern-j `following isa full, clear, and exact dei scri tion.

lV y invention relates to clutches designed to be used as guards for scarf pins, and has for its principal object, to provide 4means adapted to prevent a scarf pin from working loose from a scarf, or from being surreptitiously removed therefrom. This I accomf plish by the means hereinafter described and illustrated in the accompanying drawings,

bodied in the form preferred by me, and wherein similar characters of reference in dicate l corresponding parts throughout the several views.

In the drawings, Figure '1, is a vertical longitudinal section of a scarf pin guard embodying my invention showing a scarf pin applied thereto. Fig. 2 is a horizontal section taken yon the line 2-2 of Fig. l. i As illustrated in the drawings, l represents a tubular casing, preferablyreduced in diameter at the end 2having an insertion opening 3. The opposite end of the casing is provided with an inclined inner end wal] et, flaring outwardly in a direction opposite to the insertion end ofthe casing and forming a recess, adapted to receive a. head 5, having an inclined wall 6 corresponding in a general way with the inclined inner end wall of the casing. The head 5 is provided with a central aperture 7 adapted to receive a scarf pin 8, and with lateral apertures or recesses t), for holding frictional lballs 10, or other gripping devices adapted to bear against the inner inclined end wall L1 of the casing, and also against a scarf pin 8 inserted in the central aperture 7 of said head. The head 5 is. also provided with `a tubular stem 12, extending through an Iaperture 13 inthe conicalfend wall of the casing, which is preferably made large enough to allow the inner end ofsald stem to pass through and up into the interior of the casing. The lextremity 14 'of said 'stem is preferably Haring to permit the point of a scarf pin to be readily inserted in said stern. A spring 15, is arranged Within the casing, between said head and the insertion head 5 inwardly,"

clined end wall 4 end of the casing and bears against the stem 12`so as to n thereby bringing the frictional or gripping devices against the-inof the'casing and against a scarf pin extending through said head 5.

To operate the clutch or guard, the point-- ed 'endof as'carf pinis inserted through aperture 3 of the reduced end 2 of the y Patented Jan. 16,1912'.

press said stern and the casing into the stern 12 and through the head 5. The downward pressure of thefnd of the pin against the balls 10 head 5 outward slightly against thetension of said spring 15, thereby permitting the end ofthe pin to pass between'the balls 10, and fout through the head 5." downward pressure on the pin istreleased, the spring l5, forces the stem 12v inward, at

the Sametime moving the head 5 toward.

the inclined inner wall 4 and pressing the friction devices l0 against said end wall. The vfriction balls 10 are thereby pressed laterally against the shank of the pin ,eX-

tending through the head 5, and revent the pin from beconnng loose, or rom being removed from the scarf without the knowledge or consent of t-he wearer.

It is apparent that if an effort be made to remove thepin from the Scarf of a wearer, an upward pull of the pin, whilegripped by the balls l() will tend to pull the head 5 presses thefarther inward in the recess in the end of the casing,yand bring the ballslO into a.

.more contracted portion of the recess and consequently cause the balls to grip the pin more tightly.

- When it is desired by the user to release the pin, the head 5 is pulled outward slightly frgni the end wall of the casing, by

means of'a rim 11, which overlaps the ad-l ljacent end of the casing and extends outward laterally therefrom, the friction balls 1() into a recess, and when in such tion balls 10 relax their tliere'by 'bringing position, the fricrip on the pin and permit the pin to betreadily withdrawn from the guard.

As shown in the drawings, the end wall et' is formed independently 'of the body of the wider part of said.

loo

casing and is secured thereto in any suitable manner, as by turning over the adjacent edge 16 of thecasing onto the .outer edge 17 of the end wall 4. By means of such con struction, the tubular stein 12 may be passed through the aperture 13 ofthe end wall and l the spring 16 arranged in position before the end wall is set permanently in the casing. The end wail of the easing may however he formed integral with the body of the casing without departing from my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters-PatentJ is:

l. A. Scart1 pin guard, comprising a cas` ing having an insertion opening at one end and at the opposite end an inner end wail inclined inwardly forming a recess and pro` vided with an aperture, a head withinsaid recess provided with an aperture to receive a scarf pin and with a stein extending through said end wall into the interior of said casing, apin gripping device mounted in said head adapted to bear against one side of said end wall, and a spring within said casing on the opposite side of said end wall adapted to press f uid stem and head normally inward.

2. A scarf pin guard, comprising a cas- YQ l 1,015,266

within said casing between the inner sidev of said end Wall and insertion end of said casing to press said stemand head normally inward.

In witness whereoi I have hereunto set my signature in the presence of two attesting witnesses. l
